高温气冷实验堆燃料元件双向探测器的研制

Development of bi-directional detector for the fuel element in high temperature gas cooled reactor

介绍了高温气冷实验堆燃料元件双向探测器的基本原理和实现方法。它以两个并联的感应线圈为敏感元件 ,通过双通道法采集信号 ,以 89C51单片机为处理核心 ,系统软件采用循环扫描输入端口的方式获取过球信号 ,经智能分析、判断 ,实现了对燃料元件的双向检测。

The basic principle and the implement method of bi directional detector for fuel handling system in 10MW high temperature gas cooled reactor were studied in this paper. Two inductor coils in parallel connection were used as the sensitive element and two channel circuit were chosen in the signal sampling circuit, a 89C51 microprocessor was applied as the processing core, the ball passing signals were acquired on the input port through the mode of circulate scan in the system program and analyzed by the intelligence technology, the function of the bi directional detection of fuel element was realized.
